Zhou and his colleagues considered a well-established technique known as reconstruction of attosecond beating by interference of two-photon transitions (RABBIT). In RABBIT, a train of ...

The new JWST observatory is revealing far more bright galaxies in the early Universe than anyone predicted, and astrophysicists have more than one explanation for the puzzle. With the JWST observatory ...

The demonstration that ions can be precisely manipulated in a trap containing integrated photonics paves the way for a large-scale trapped-ion quantum processor. Figure 1: Mordini and colleagues ...

Scientists have pinpointed energy-efficient ways to cook al dente pasta and developed an infallible recipe for the perfect cacio e pepe sauce. The study by Toultchinski and Vilgis was inspired by a ...

A device’s selective interaction with left- and right-propagating modes could pave the way for directional information flow in quantum computing based on superconducting circuits. Figure 1: An emitter ...

Top quarks and antiquarks have been detected in heavy-ion collisions at the Large Hadron Collider, showing that all six quark flavors were present in the Universe’s first moments. The ATLAS ...

Natural engineering. The bird’s nest achieves cohesion and flexibility by the interweaving of bendy rods in frictional contact. × A bird’s nest is a marvel of natural engineering: a disordered bundle ...

Particle physicists are faced with a growing list of “anomalies”—experimental results that conflict with the standard model but fail to overturn it for lack of sufficient evidence. For their study of ...

A “Little Earth Experiment” inside a giant magnet sheds light on so-far-unexplained flow patterns in Earth’s interior. Sketch of outer-core flows derived from data from the Swarm mission (plotted ...

String theory provides a microscopic description of the entropy of certain theoretical black holes—an important step toward understanding black hole thermodynamics. Figure 1: Through the AdS/CFT ...

A new analysis of more than a decade’s worth of observations extends the spectrum of cosmic-ray electrons to unprecedented high energies. Cosmic-ray electrons are high-energy particles that lose ...

Jungsang Kim is a professor of Electrical and Computer Engineering, Physics, and Computer Science at Duke University in North Carolina. He leads the Multifunctional Integrated Systems Technology group ...
